Add AI Chat

We are converting an already launched internal implementation of an
Angular AI Chat to Lit. That is why so much code is being written in
one change. Most of this code has already been launched in its
Angular version.

The AI Chat UI is definitely not bug free and not feature complete yet.
But it is gated by a flag, so we will continue to iterate on this new
UI before launching to users outside of the team.

This change introduces a new AI-powered chat panel in the change view
sidebar. Users can open the panel to interact with a review assistant,
ask questions about the change, and use predefined actions.

The implementation includes:

* A new set of Lit components under polygerrit-ui/app/elements/chat-panel/ that build the UI for the chat experience, including a splash page, conversation history, and message rendering.

* A new ChatModel to manage the state of conversations, including turns, user input, context items, and communication with the AI provider.

* A significant expansion of the Plugin API to support chat functionality. This defines the contract for streaming responses, conversation history, available actions/models, and context management.

* An update to gr-change-view to use gr-content-with-sidebar to host the new chat-panel component.

* A new cryptoUuid utility for generating unique conversation IDs.

* The minimum width of the sidebar in gr-content-with-sidebar is increased to 400px to better accommodate the chat panel.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Build Status Maven Central

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The Developer Mailing list is repo-discuss on Google Groups.

License

Gerrit is provided under the Apache License 2.0.

Build

Install Bazel and run the following:

    git clone --recurse-submodules https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update && apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

On Fedora run:

    dnf clean all && dnf install gerrit-<version>[-<release>]

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 8 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-centos8

To run a Ubuntu 20.04 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-ubuntu20

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
